The Chronians were once a great race, but the misuse of their own abilities trapped Chronia and themselves outside time and space. Eon was the only known Chronian to escape this.

Planning to conquer Earth, the Chronians were freed when Eon used the Hands of Armageddon to open a time rift between Earth and Chronia, but the Chronian invasion was sent back when Max Tennyson deactivated the Hands.

Chronians possess time manipulation powers, thus controlling time itself. They can fire energy blasts and produce energy spheres (for purposes such as offensive attacks or for activating Chronian technology). They can also teleport, leaving behind a purple residue. Chronians can freeze time, reverse it for certain individuals, or age other living things into a dessicated, zombie-like state "in the blink of an eye." Chronians can even use their powers to manipulate and control technology such as vehicles and clockwork gears.

Though very powerful, especially as an entire species, Chronians' powers can backfire on them if they misuse them; this is how the Chronian race became trapped outside of time. It would also seem that overusing their powers weakens Chronians and speeds up their ageing process. A Chronian can be incapacitated via cryo-stasis, although this is not necessarily a permanent solution. It has been shown as well that Chronians, like humans, possess an average- or below-average pain tolerance, meaning they can be momentarily hurt and stunned by physical strikes or electrocution.

The name "Chronian" comes from the name "Kronos", "Cronus", or "Chronos", the name of the Titan Lord of Fate, Harvest, Justice, and Time, or more essentially the Titan God of Time, from Greek and Roman mythologies.
